The Search for a Second Genesis of Life in Our Solar System

  • Christopher P. McKay

Abstract

One of the key goals of Astrobiology is to search for another example of life. In the near term, Mars and Europa are the likely targets for a search for a second genesis. On Mars the search is likely to be conducted in the frozen permafrost. On Europa active life may be found in the ocean beneath the ice cover.
